Description

  The present invention relates to a horizontal blade and an air conditioner, and more particularly, to a horizontal blade for changing the blowing direction of conditioned air, and an air conditioner including the horizontal blade.

  The wall-mounted indoor unit of the air conditioner includes an indoor heat exchanger in the casing body. The wall-mounted indoor unit sucks room air into the casing body using a blower fan such as a cross-flow fan, passes the sucked room air through the indoor heat exchanger, and harmonizes the air from the air outlet to the outside of the casing body. Is blowing out. In order to control the wind direction of the conditioned air blown out from the air outlet, the wall-mounted indoor unit is generally provided with a vertical blade for adjusting the wind direction in the left-right direction and a horizontal blade for adjusting the wind direction in the vertical direction. is there.

  Generally, the outlet of a conventional wall-mounted indoor unit is provided on the front surface of the indoor unit or the bottom surface of the indoor unit. When placing importance on the appearance of the indoor unit for harmony with the interior of the room, the air outlet is blocked by the horizontal blades when the indoor unit is stopped, and the vertical wind direction is adjusted by the horizontal blades when the indoor unit is in operation. May be adopted. When such a structure is adopted, the horizontal blade is the same length as the outlet, that is, shorter than the length of the casing body in the longitudinal direction.

  When air outlets are provided on the front surface of the indoor unit or the bottom surface of the indoor unit in this way, because of the depth of the indoor unit, conditioned air is delivered to the zone close to the wall surface on which the wall-mounted indoor unit is attached. It becomes difficult. Since the wind direction of the conditioned air blown out from the air outlet has a predetermined angle with respect to the wall surface, this tendency becomes more prominent as the distance from the indoor unit becomes longer.

  Therefore, for example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2006-2984), the horizontal blades are configured to be open on the left and right side surfaces of the casing body with the horizontal blades closed, and blown out from these openings to the left and right. It has been proposed to form a wind flow.

  However, in the case of the wall-mounted indoor unit of Patent Document 1, the strength in the left-right direction can be changed by the vertical blades, but the wind direction is limited to the horizontal direction, and guidance to the direction that penetrates the horizontal blades in the left-right direction, etc. Was difficult. Also, if large openings are provided on the left and right side surfaces, it becomes a design noise and deteriorates the interior property of the indoor unit.

  The subject of this invention is providing the horizontal blade | wing which can increase the variation of the change of a wind direction also including the left-right direction, and is easy to improve the aesthetics of an indoor unit.

  The horizontal blade | wing which concerns on 1st invention is provided in the front of the blower outlet so that the wind direction of the air blown from a blower outlet can be changed up and down in the direction ahead of a blower outlet. And as for the horizontal blade | wing, the left side slit and the right side slit for blowing off the air which blows off from a blower outlet in the left-right direction along the longitudinal direction of a blower outlet are formed in the left-right edge part vicinity.

  According to the present invention, since the airflow along the surface of the horizontal blade is different from the airflow passing through the left slit and the right slit, variations in the airflow can be increased by utilizing these differences. In addition, by providing the left and right slits in the horizontal blade, it is not necessary to provide an opening in the side surface portion, so there is no problem with the left and right sides, and it becomes easy to finish in a refined shape.

  The horizontal blade | wing which concerns on 2nd invention is a horizontal blade | wing of 1st invention, Comprising: A horizontal blowing induction | guidance | derivation part has at least one periphery of a left side slit and a right side slit. The horizontal blowing guiding portion bends the flow direction of the air blown from the blower outlet in the horizontal direction and guides it to at least one of the left slit and the right slit.

  According to the present invention, it becomes easy to guide conditioned air to the left side slit and / or the right side slit provided with the side blowing induction part by the side blowing induction part, and the effect of side blowing by the left side slit and / or the right side slit is improved. be able to.

  The horizontal blade | wing which concerns on 3rd invention is a horizontal blade | wing of 1st invention or 2nd invention, Comprising: A main-body part is provided in order to cover at least one part of a blower outlet at the time of closing of a blower outlet. This main body changes the wind direction of the conditioned air up and down when the air outlet is opened. Further, a left side surface portion is formed at the left end of the main body portion so as to bend toward the air outlet rather than the main body portion. A left side slit is disposed on the left side surface portion. Similarly, a right side surface portion is formed at the right end of the main body portion so as to bend toward the air outlet rather than the main body portion. A right slit is disposed on the right side surface portion.

  According to the present invention, since the airflow flowing to the left without passing through the left slit can be weakened by the left side surface portion, the conditioned air constituting the airflow blown to the left is almost limited to that having passed through the left slit. Similarly, since the airflow flowing to the right without passing through the right slit can be weakened by the right side surface portion, the conditioned air constituting the airflow blown to the right is almost limited to that having passed through the right slit. By arranging the left side slit and the right side slit in such a place, it is possible to cope with a design in which the region of the air flow blown to the left and right is limited and the air is blown strongly to the left and right.

(Overview of indoor unit)
FIG. 1 is a front view of an indoor unit of an air conditioner according to an embodiment of the present invention, FIG. 2 is a bottom view of the indoor unit, FIG. 3 is a right side view of the indoor unit, and FIG. It is a perspective view which shows the indoor unit seen from diagonally lower right. In the indoor unit 1, five surfaces other than the front surface 1 a, the left side surface 1 b, the right side surface 1 c, the top surface 1 d and the bottom surface 1 e, that is, the back surface 1 f of the casing body 2 are covered with the decorative panel 5. In the following description, the direction from the rear surface 1f of the indoor unit 1 to the front surface 1a (front surface) is referred to as the front, and is along the direction connecting the left side surface 1b and the right side surface 1c of the indoor unit 1, that is, the longitudinal direction of the outlet 4. The direction is called the left-right direction.

  The indoor unit 1 includes a suction port 3 on the top surface 1d of the casing body 2 and a blower port 4 on the bottom surface 1e. FIG. 1 shows a state in which the horizontal blade 6 provided at the air outlet 4 is bound. Normally, the air outlet 4 is closed when the operation is stopped, and the air outlet 4 is opened during the operation. However, the indoor unit 1 in FIG. 1 blows out conditioned air in the left-right direction even when the air outlet 4 is closed by the horizontal blades 6. Can do. Details of the operation of the indoor unit 1 will be described later. In the following description, the expression that the horizontal blade 6 closes the outlet 4 is used to express the state in which there is no gap between the outlet 4 and the horizontal blade 6 for blowing out conditioned air, and the horizontal blade 6 uses the outlet 4. The expression “cover” is used as an expression that allows the closing operation with or without a gap for blowing out conditioned air with an emphasis on explanation.

  In the indoor unit 1 shown in FIG. 1, indoor air is not sucked from the front surface 1 a, and the indoor unit 1 sucks indoor air exclusively from the suction port 3 on the top surface 1 d of the casing body 2. Therefore, the circulation of the indoor air inside the indoor unit 1 is performed from the top surface 1d side of the indoor unit 1 toward the bottom surface 1e side of the indoor unit 1. As shown in FIG. 3, a cross flow fan 7 is provided inside the casing main body 2 of such an indoor unit 1 near the rear side at the substantially center of the casing main body 2 in a side view. An upstream heat exchanger (not shown) having an inverted V shape in a side view is disposed on the upstream side of the cross flow fan 7, and the indoor heat exchanger is connected to the room air before being sucked into the cross flow fan 7. Air conditioning is performed by passing through. In addition, an air filter (not shown) is provided upstream of the indoor heat exchanger, and dust larger than the gap of the air filter is completely removed from the conditioned air guided to the cross flow fan 7. Although illustration is omitted, in the front view, the cross flow fan 7 has the same length as the suction port 3 and is long and horizontally disposed along the longitudinal direction of the casing body 2. Thus, in order to perform indoor air conditioning efficiently by sucking indoor air and blowing out conditioned air by the crossflow fan 7 extending long in the longitudinal direction of the casing main body 2, the indoor heat exchanger is also provided in the casing main body 2. It is formed in a shape that extends long in the longitudinal direction, and is disposed between the suction port 3 and the blower port 4 that extend long.

  Between the crossflow fan 7 and the blower outlet 4, as shown in FIG. 3, the blower channel | path 8 of a diffuser structure is provided. The guide surface 8a of the blow-out passage 8 has a smooth curve having a center of curvature on the side of the cross flow fan 7 in a side view, and the radius of curvature increases toward the lower side. Further, since the cross flow fan 7 rotates clockwise as viewed from the right side and its central axis is disposed toward the back surface 1f, the blowout passage 8 is located on the front side of the bottom surface 1e. It is formed obliquely toward Therefore, the conditioned air from the outlet passage 8 toward the outlet 4 has a directional vector from the top surface 1d toward the bottom surface 1e and a directional vector from the back surface 1f toward the front surface 1a. Become.

<Configuration of wind direction device>
A horizontal blade 6 is provided in front of the air outlet 4. The horizontal blade 6 can take two states, that is, when it is opened during operation and when it is operated while being closed. The indoor unit 1 can adjust the wind direction in the vertical direction of the indoor unit 1 by the horizontal blades 6. In this indoor unit 1, the horizontal blade 6 is opened when the air is blown forward from the air outlet 4 during heating and cooling, and the horizontal blade 6 is closed when the air is blown only right and left from the air outlet 4. FIG. 1 shows a state in which the air outlet 4 is closed with the horizontal blades 6 closed.

  FIG. 5 is a perspective view showing the indoor unit 1 as viewed from the lower left, and shows a state in which the horizontal blades 6 are removed for easy explanation of the internal structure of the blowout passage 8. A plurality of vertical blades 9 connected by vertical blade connecting rods 10 are swingably attached to the blowing passage 8. The surfaces 9 a of the plurality of vertical blades 9 swing left and right about a state perpendicular to the longitudinal direction of the casing body 2. These vertical blades 9 adjust the right and left direction of the conditioned air blowing direction by swinging or stopping at an arbitrary angle after swinging. Since the vertical blades 9 are connected by the two vertical blade connecting rods 10, they can be divided into two groups, a group A near the left side surface 1b and a group B near the right side surface 1c. The swinging direction is independent between group A and group B connected to different vertical blade connecting rods 10. For example, when group A is tilted to the right, group B may be tilted to the left. Further, in the group A and the group B, for example, even when they are tilted in the same direction, the tilt angles can be made different. Of course, the vertical blades 9 belonging to the group A and the group B can be swung in the same direction.

  In FIG. 5, the position indicated by the two-dot chain line 11 is an extension of the ridge line that is the boundary between the bottom surface 1 e and the right side surface 1 c. Conventionally, the decorative panel 5 on the right side surface 1c usually exists up to the two-dot chain line 11. That is, the portion where the bottom surface 1e on the two-dot chain line 11 is recessed becomes an opening 12c for blowing to the right. The blower outlet 4 includes this opening 12c. Similarly, the bottom surface 1e is recessed on the left side, and the outlet 4 includes the opening 12b. The opening part 12a of the bottom face 1e of the blower outlet 4 is between these opening parts 12b and 12c. Thus, since the blower outlet 4 has the opening part 12b on the left side and the opening part 12c on the right side, the shape of the horizontal blade | wing 6 is also adapted to it.

  Next, the structure of the horizontal blade 6 will be described. FIG. 6A shows the front of the horizontal blade, FIG. 6B shows the bottom of the horizontal blade, and FIG. 6C shows the right side of the horizontal blade. Further, FIG. 7A shows a perspective view of the horizontal blade, and FIG. 7B shows a partially enlarged view of the right side surface portion as viewed obliquely from the upper left. The horizontal blade 6 includes a main body portion 6a, a left side surface portion 6b extending further to the left from the left end of the main body portion 6a, and a right side surface portion 6c extending further to the right from the right end of the main body portion 6a. In a closed state, the horizontal blade 6 is configured such that the left side surface portion 6b closes the opening portion 12a of the left side surface 1b, and the right side surface portion 6c closes the opening portion 12b of the right side surface 1c.

  The front end portion 6d and the rear end portion 6e of the horizontal blade 6 are connected in a straight line between the left side surface portion 6b and the right side surface portion 6c in the main body portion 6a. The left end portion 6f of the left side surface portion 6b and the right end portion 6g of the right side surface portion 6c continue from the front end portion 6d to the rear end portion 6e so as to draw a parabola, and the rear end portions of the left side surface portion 6b and the right side surface portion 6c It extends from the rear end 6e of the portion 6a and is connected to the left end 6f and the right end 6g.

  Referring to FIG. 6C, the bottom surface 6h of the main body portion 6a is warped in a bow shape from the rear end portion 6e to the front end portion 6d in a side view. Since the main body 6a of the horizontal blade 6 is normally supported by two or three points by a movable arm or the like, it is necessary to increase rigidity so as not to bend and to prevent condensation on the horizontal blade 6 or the like. In order to give heat insulation, it has a predetermined thickness. Therefore, the thickness gradually increases along the shape of the bottom surface 6h in a side view from the front end portion 6d to the ridge line 6j, and a relatively flat upper surface 6i continues with some unevenness, and extends from the ridge line 6j to the rear end portion 6e. The thickness decreases rapidly. In a state where the horizontal blade 6 closes the air outlet 4, the flat upper surface 6i of the main body 6a is kept substantially horizontal.

  A left side slit 13 and a right side slit 14 are formed in the left side surface part 6b and the right side surface part 6c of the horizontal blade 6, respectively. The left slit 13 is composed of an upper left slit 13a and a lower left slit 13b, and the right slit 14 is composed of an upper right slit 14a and a lower right slit 14b. The lower left slit 13b is formed between the slope 6k and the slope 6m. The slope 6k is a slope that reaches the vicinity of the left end of the bottom surface 6h obliquely from the upper surface 6i at the left end of the main body 6a. In the left side surface portion 6b, the inclined surface 6m extends horizontally from the middle height between the rear end upper portion 6b1 and the rear end portion e toward the vicinity of the front end portion 6d. The lower right slit 14b is formed between the slope 6l and the slope 6n. The inclined surface 6l is an inclined surface that reaches the vicinity of the right end portion of the bottom surface 6h obliquely from the upper surface 6i at the right end portion of the main body portion 6a. The slope 6n extends horizontally from the middle height between the rear end upper portion 6b1 in the left side surface portion 6b and the rear end upper portion 6c1 and the rear end portion e in the right side surface portion 6c toward the vicinity of the front end portion 6d.

  A left horizontal blowing guide plate 15 is formed between the lower left slit 13b and the upper left slit 13a, and a right horizontal blowing guide plate 16 is formed between the lower right slit 14b and the upper right slit 14a. The left side blowing guide plate 15 and the right side blowing guide plate 16 are formed so as to partially overlap with the slopes 6k and 6l in plan view, but not to overlap most. Further, the left side blowing guide plate 15 and the right side blowing guide plate 16 are inclined downward toward the left side surface portion 6b and the right side surface portion 6c, respectively. Therefore, the conditioned air blown directly from the outlet 4 toward the slopes 6k and 6l is guided obliquely downward toward the left and right ends along the slopes 6k and 6l, and passes through the lower left slit 13b and the lower right slit 14b. The left side surface portion 6b and the right side surface portion 6c are blown out obliquely downward to the left and right. In addition, the conditioned air traveling toward the left and right ends along the main body 6a is closer to the upper surface 6i than the left side blowing guide plate 15 and the right side blowing guide plate 16, and is moved upward by the left side blowing guide plate 15 and the right side blowing guide plate 16. The flow is restricted so as not to escape to the lower left slit 13b and the lower right slit 14b.

  The air heading toward the left side blowing guide plate 15 and the right side blowing guide plate 16 from above is guided diagonally downward toward the left and right ends by the left side blowing guide plate 15 and the right side blowing guide plate 16, and the upper left slit 13a and the upper right slit 14a. , And blown obliquely downward from the left side surface portion 6b and the right side surface portion 6c to the left and right. Auxiliary plates 17 and 18 are formed around the upper part of the upper left slit 13a and the upper right slit 14a to suppress the airflow directed upward from the horizontal blades 6.

  The wind direction device includes a horizontal blade driving mechanism that drives the horizontal blade 6 in order to adjust the angle when the horizontal blade 6 is opened and closed and opened. The horizontal blade drive mechanism includes three arms 40, 41, and 42 arranged in parallel to each other at the center in the longitudinal direction of the casing body 2 and on the left and right sides thereof (see FIG. 10). The three arms 40, 41, and 42 are moved (protruded) so as to extend obliquely downward toward the front by a rack and pinion mechanism (not shown), or moved in the opposite direction to be stored. Or Since these arms 40, 41 and 42 are driven by the rack and pinion mechanism so that the movement amounts are the same, the movement of the horizontal blades 6 supported by the arms 40, 41 and 42 by the rack and pinion mechanism is It becomes translation. The arms 40, 41, and 42 are attached to the horizontal blade 6 via a drive shaft (not shown) on the same axis, and the horizontal blade 6 can be rotated around the axis of the drive shaft. The wind direction device combines the parallel movement and the rotational movement of the horizontal blade 6 by adjusting the amount of projection of the arms 40, 41 and 42 by the rack and pinion mechanism and adjusting the rotation angle of the horizontal blade 6 by the drive shaft. The horizontal blade 6 can take various postures. For example, the horizontal blade | wing 6 can take the attitude | position in which the upper surface 6i of the main-body part 6a of the flat horizontal blade | wing 6 becomes horizontal.

  As described above, the air direction device of the air conditioner includes the horizontal blades 6 and the vertical blades 9, and the horizontal blade driving mechanism and the vertical blade driving mechanism for driving them. The vertical blade driving mechanism has the above-described vertical blade connecting rod 10 in order to drive the vertical blade 9. Control of the horizontal blade driving mechanism and the vertical blade driving mechanism will be described later.

  By adjusting the blowing direction of the horizontal blade 6 and the vertical blade 9 and adjusting the wind speed of the cross flow fan 7, appropriate air conditioning corresponding to the indoor form and the indoor situation can be performed. In order to control the horizontal blades 6, the vertical blades 9, and the cross flow fan 7, a control unit 20 as shown in FIG. 8 is provided. The control unit 20 includes an indoor control unit 21 for controlling each device of the indoor unit 1 and an outdoor control unit 22 for controlling each device of the outdoor unit, and the indoor control unit 21 and the outdoor control unit. 22 is connected by a signal line 23.

  The outdoor control unit 22 is connected to a compressor 24, an outdoor electric expansion valve 25, a four-way switching valve 26, an outdoor fan 27, a plurality of pressure sensors 28, a plurality of temperature sensors 29, and the like. The outdoor control unit 22 controls the refrigerant circulation amount of the refrigerant circuit by controlling the rotational speed of the compressor 24, for example, and controls the pressure of the refrigerant flowing through the refrigerant circuit by controlling the opening degree of the outdoor electric expansion valve 25. To do. The outdoor control unit 22 switches the circulation path of the refrigerant flowing in the refrigeration circuit by switching the four-way switching valve 26 to control operation switching such as switching between heating operation and cooling operation. The outdoor control unit 22 controls the heat exchange efficiency in the outdoor heat exchanger by controlling the rotational speed of the outdoor fan 27. Therefore, the outdoor control unit 22 uses the temperature and pressure of each part detected by a plurality of pressure sensors 28 and temperature sensors 29 installed in the refrigerant circuit and each device for judgment for control.

  On the other hand, the indoor control unit 21 is connected to a transmission / reception unit 30, a horizontal blade drive mechanism 31, a vertical blade drive mechanism 32, a crossflow fan motor 33, a plurality of temperature sensors 34, a display unit 35, and the like. The indoor control unit 21 transmits and receives data between the user's remote controller and the transmission / reception unit 30 for control. The indoor control unit 21 controls the horizontal blade driving mechanism 31, the vertical blade driving mechanism 32, and the crossflow fan motor 33 in accordance with the indoor state and the setting of the user, and controls the angle of the horizontal blade 6 and the vertical blade 9 or the like. The swinging state and the rotational speed of the cross flow fan motor 33 can be adjusted to change the blowing direction and the strength of blowing the conditioned air. The indoor control unit 21 uses state information such as the temperature of each part detected by a plurality of temperature sensors 29 or the like installed in the refrigerant circuit or each device for judgment for control. In addition, the indoor control unit 21 notifies the user of the setting state and environment of the indoor unit 1 via the display unit 35.

<Operation of wind direction device>
When the indoor unit 1 is normally stopped, the horizontal blades 6 are closed as described with reference to FIGS. This prevents dust or pollen from accumulating on the horizontal blade 6 when the indoor unit 1 is stopped. As shown in FIGS. 6 and 7, the horizontal blade 6 is formed with a left side slit 13 and a right side slit 14. However, since the left side surface portion 6b and the right side surface portion 6c of the horizontal blade 6 are curved, the left side slit 13 and the right side slit 14 are not the left side surface 1b and the right side surface 1c of the indoor unit 1, but rather the bottom surface of the indoor unit 1. 1e. Further, since the slopes 6k, 6l, the left side blowing guide plate 15 and the right side blowing guide plate 16 are inclined obliquely downward, the horizontal blades 6 are closed so that dust, pollen and the like are not easily accumulated.

(Blow left and right)
FIG. 9 is a partially enlarged view showing the state of the indoor unit as viewed from the front side on the lower right. FIG. 9 shows a state in which conditioned air is blown out only in the left-right direction with the horizontal blades 6 closed. Also, in FIGS. 1 to 4 described above, the conditioned air blowing direction in this state is indicated by arrows. At this time, the indoor control unit 21 of the control unit 20 outputs an instruction signal to the horizontal blade driving mechanism 31 so that the horizontal blade 6 is closed. In order to make it easier to blow right and left, the indoor control unit 21 outputs an instruction signal to the vertical blade drive mechanism 32 so that the group A of the vertical blades 9 tilts to the left and the group B tilts to change the airflow to the right. To do. Accordingly, for example, as shown in FIG. 9, if it is on the right side, conditioned air is blown out from the upper right slit 14 a and the lower right slit 14 b toward the lower right direction D 1, D 2 of the indoor unit 1. For example, since the direction D2 of the conditioned air blown out from the lower right slit 14b is regulated by the angle between the slope 6m and the lower surface of the right side blowing guide plate 16, the direction D2 is set depending on how this angle is formed. can do.

  Here, the case where the right side blowing guide plate 16 is fixed has been described. However, the angle of the lower surface of the right side blowing guide plate 16 can be changed and changed, and in that case, manually or The direction D2 can be automatically changed according to the situation. The direction D1 can also be set by the angle of the upper surface of the right side blowing guide plate 16 as in the direction D2. An instruction signal is output from the indoor control unit 21 to the crossflow fan motor 33 so as to set the rotation speed of the crossflow fan 7 to an appropriate value.

(Blowout during cooling operation)
FIG. 10A shows a front view of the indoor unit during the cooling operation, and FIG. 10B shows a bottom view of the indoor unit during the cooling operation. Further, FIG. 11A shows a side view of the indoor unit during the cooling operation, and FIG. 11B shows a perspective view of the indoor unit during the cooling operation. During the cooling operation, the front end portion 6d of the horizontal blade 6 is lowered from the rear end portion 6e, and the upper surface 6i of the horizontal blade 6 is inclined, for example, about 30 degrees with respect to the horizontal. In order to bring the horizontal blade 6 suspended by the central arm 40 and the left and right arms 41 and 42 into the state shown in FIGS. 10 and 11, the horizontal blade 6 is pushed out by extending the arms 40, 41 and 42. It is necessary to perform the operation and the operation of changing the angle of the horizontal blade 6 with respect to the arm 40 by the drive shaft 43 at the tip of the arm 40. When the conditioned air is blown out from the outlet 4 in a state where the horizontal blades 6 are opened at the angles shown in FIGS. 10 and 11, from between the front end portion 6 d of the horizontal blade 6 and the bottom surface 1 e of the indoor unit 1. A conditioned air flow toward the front is formed. The conditioned air is conveyed toward the wall on the opposite side of the indoor wall to which the indoor unit 1 is attached by this air flow.

  At this time, if the vertical blade 9 is fixed perpendicularly to the longitudinal direction of the casing body 2, the conditioned air blown from the outlet 4 is not guided to the left slit 13 and the right slit 14 at both the left and right ends of the horizontal blade 6. . When the vertical blades 9 are fixed vertically as described above, almost all of the conditioned air flows straight forward. The direction of the airflow at this time is indicated by an arrow in FIG. In this case, the forward flow is smooth due to the left side surface portion 6b and the right side surface portion 6c. On the other hand, the vertical blade 9 can be adjusted to an angle at which the conditioned air does not reach the left slit 13 and the right slit 14 at both left and right ends while the vertical blade 9 is tilted left and right. In this case, the conditioned air flowing forward by the horizontal blades 6 spreads in a fan shape. The direction of the airflow at this time is indicated by an arrow in FIG. Further, the vertical blade 9 can be tilted to the left and right so that the conditioned air reaches the left slit 13 and the right slit 14 at both left and right ends. In this case, not only the conditioned air flowing forward by the horizontal blades 6 spreads out in a fan shape, but also the conditioned air that has passed through the left slit 13 is transmitted to the left side blowing guide plate 15 and the right side blowing guide plate 16 or the slope 6k, It flows in the left-right direction along 6l. The direction of the airflow at this time is indicated by an arrow in FIG. In this case, the left side blowing guide plate 15 and the right side blowing guide plate 16 and the slopes 6k, 6l are angled with respect to the upper surface 6i of the horizontal blade 6, thereby giving the airflow a slightly rearward direction vector. be able to. With such a setting, the conditioned air can be blown into a zone along the wall just beside the indoor unit 1, which is difficult to guide only with the vertical blades 9 due to the depth of the indoor unit 1. Note that the right side blowing guide plate 16 may be configured to blow rightward without giving an angle.

  At this time, by changing the angle of the horizontal blade 6, the strength of the airflow in the left-right direction can be changed. For example, the closer the upper surface 6i of the horizontal blade 6 is to a direction perpendicular to the direction of the laminar flow blown out from the blower outlet 4, the weaker the strength toward the front of the airflow is, while moving in the left-right direction. Increases the strength of the airflow.

(Blowout during heating operation)
FIG. 12A shows a front view of the indoor unit during the heating operation, and FIG. 12B shows a bottom view of the indoor unit during the heating operation. FIG. 13A shows a side view of the indoor unit during the heating operation, and FIG. 13B shows a perspective view of the indoor unit during the heating operation. During the heating operation, the rear end portion 6e of the horizontal blade 6 is below the front end portion 6d, and the upper surface 6i of the horizontal blade 6 is substantially vertical. In the state shown in FIGS. 12 and 13, the rear end portion 6 e protrudes forward and the upper surface 6 i faces slightly downward from the state in which the upper surface 6 i is substantially vertical. In order to make the horizontal blade 6 suspended by the central arm 40 and the left and right arms 41, 42 into the state shown in FIGS. 12 and 13, the arms 40, 41, 42 use the horizontal blades as in the above cooling operation. 6 is pushed out, and the horizontal blade 6 is changed to a vertical state by the drive shaft 43 at the tip of the arm 40. When the conditioned air is blown out from the outlet 4 in a state where the horizontal blades 6 are opened at the angles shown in FIGS. 12 and 13, the conditioned air is blocked by the horizontal blades 6 and flows downward.

  At this time, if the vertical blade 9 is fixed perpendicularly to the longitudinal direction of the casing body 2, the conditioned air blown from the outlet 4 is guided to the left slit 13 and the right slit 14 at the left and right ends of the horizontal blade 6. Rather, almost all conditioned air flows straight down. At this time, due to the left side surface portion 6b and the right side surface portion 6c, the downward flow becomes smooth. On the other hand, the vertical blade 9 is tilted to the left and right so that the conditioned air does not reach the left slit 13 and the right slit 14 at both left and right ends, and the conditioned air flowing downward by the horizontal blade 6 can be fan-shaped. it can. The direction of the airflow at this time is indicated by an arrow in FIG. Further, the vertical blade 9 can be tilted to the left and right so that the conditioned air reaches the left slit 13 and the right slit 14 at both left and right ends. In this case, not only the conditioned air flowing forward by the horizontal blades 6 spreads out in a fan shape, but also the conditioned air that has passed through the left slit 13 is transmitted to the left side blowing guide plate 15 and the right side blowing guide plate 16 or the slope 6k, It flows in the left-right direction along 6l. At this time, since the left side blowing guide plate 15 and the right side blowing guide plate 16 and the slopes 6k and 6l have an angle with respect to the upper surface 6i of the horizontal blade 6, it is possible to give the airflow a slightly forward direction vector. it can. Thereby, the conditioned air can be blown out to a zone that is difficult to be guided only by being blocked by the horizontal blades 6 and is slightly forward on the lower side of the left and right sides of the indoor unit 1. The direction of the airflow at this time is shown in FIGS. 12 (a) and 12 (b). During the heating operation, the angle of the horizontal blade 6 can be changed. For example, the closer the upper surface 6i of the horizontal blade 6 is to a direction perpendicular to the direction of the laminar flow blown out from the blower outlet 4, the weaker the strength toward the front of the airflow is, while moving in the left-right direction. Increases the strength of the airflow.

(Blowout in insensitive airflow mode)
In the following description, the conditioned air blowing mode that makes the air flow very weak so that the human body hardly feels the air flow is referred to as an insensitive air flow mode. FIG. 14A shows a front view of the indoor unit in the insensitive airflow mode, and FIG. 14B shows a bottom view of the indoor unit in the insensitive airflow mode. FIG. 15A shows a side view of the indoor unit in the insensitive airflow mode, and FIG. 15B shows a perspective view of the indoor unit in the insensitive airflow mode. In the insensitive airflow mode, the front end 6d of the horizontal blade 6 is slightly raised from the rear end 6e, and the upper surface 6i of the horizontal blade 6 is in a state of facing the air outlet. That is, the posture of the horizontal blade 6 in the insensitive airflow mode is substantially parallel to the posture in which the horizontal blade 6 closes the outlet 4. To bring the horizontal blade 6 suspended by the central arm 40 and the left and right arms 41 and 42 into the state shown in FIGS. 14 and 15, the horizontal blade 6 is pushed out by a predetermined amount by the arms 40, 41 and 42. Then, the rear end portion 6e of the horizontal blade 6 is slightly lowered so that the angle is adjusted by the drive shaft 43 (see FIG. 11B) at the tip of the arm 40. That is, the indoor unit 1 can open the blower outlet 4 in a state where the horizontal blade 6 is pushed out and the horizontal blade 6 is orthogonal to the airflow blown out from the blower outlet 4. If the horizontal blades 6 are kept at an angle orthogonal to the air flow blown from the outlet 4, the conditioned air strikes the horizontal blades 6 and flows not only in the front and left and right directions but also in the rear, that is, can be blown out in four directions. It becomes a state.

  The state shown in FIGS. 14 and 15 is a state in which the tip end portion 6d is slightly lower than the state in which the upper surface 6i is perpendicular to the blowing direction of the laminar flow blown from the blower outlet 4. In this state, the airflow is weakened by hitting the horizontal blades 6, but it can be said that the flow of the conditioned air to the rear is hardly present or is extremely weak. In FIG. 14 and FIG. 15, the extremely weak airflow generated at the rear is indicated by an arrow smaller than the arrows directed to the front and left and right directions. At this time, the number of rotations of the cross flow fan 7 is also reduced, and the amount of air blown from the outlet 4 is reduced. Thereby, in addition to the air volume of the conditioned air being blown off being reduced and the wind speed being weakened, the conditioned air is applied to the horizontal blades 6 to reduce the wind speed, thereby making it difficult for a person to feel the air flow. In this state, the flow of conditioned air can also be adjusted by adjusting the amount of protrusion of the arms 40, 41, and 42 to change the distance between the periphery of the outlet 4 and the horizontal blade 6.

  At this time, the airflow flowing left and right by the vertical blades 9 can be controlled in the same manner as in the cooling operation or the heating operation. Since the conditioned air that has flowed to the left and right flows along the left side blowing guide plate 15 and the right side blowing guide plate 16, it is blown to the left and right at a desired angle defined by the left side blowing guide plate 15 and the right side blowing guide plate 16.

Second Embodiment
The outline of the air conditioner according to the second embodiment is the same as that of the air conditioner of the first embodiment described above. The indoor unit of the air conditioner according to the second embodiment includes a wind direction device for the air conditioner that is different from the indoor unit of the first embodiment. The difference between the wind direction device of the second embodiment and the wind direction device of the first embodiment is the configuration of the horizontal blade drive mechanism. FIG. 16 is a perspective view of the indoor unit 1A according to the second embodiment as viewed obliquely from the lower right. The decorative panel 5 is the same in the first embodiment and the second embodiment, and the air outlet 4 has the opening 12a of the bottom surface 1e and the openings 12b and 12c provided on the left and right sides thereof. Therefore, the horizontal blade 6A has a main body portion 6Aa, a left side surface portion 6Ab, and a right side surface portion 6Ac.

<Configuration of wind direction device>
As shown in FIG. 16, the horizontal blade driving mechanism for driving the horizontal blade 6A includes a left support arm 51 and a right support arm 52 for moving the horizontal blade 6A in parallel while supporting the horizontal blade 6A. The left support arm 51 and the right support arm 52 are moved (protruded) so as to extend obliquely downward toward the front by a rack and pinion mechanism (not shown), or moved and stored in the opposite direction. To do. The left support arm 51 and the right support arm 52 are connected to the horizontal blade 6A by a ball joint (not shown) instead of being pivotally supported by the connecting portion 51a connected to the horizontal blade 6A. In the state where it is supported, not only forward and backward rotation but also left and right rotation can be handled.

  Further, the horizontal blade driving mechanism includes an intermediate support arm 50 including a rotating arm 50a, a swing arm 50b, a movable shaft 50c, and a connecting portion 50d. One end of the turning arm 50a connected to the casing body 2 is pivotally supported by a drive shaft (not shown), and can turn around the drive shaft. The other end side of the rotation arm 50a and one end side of the swing arm 50b are connected by a movable shaft 50c, and the swing arm 50b can swing around the movable shaft 50c. Further, the other end side of the swing arm 50b is supported by the horizontal blade 6A by the connecting portion 50d of the ball joint, and the swing arm 50b can swing around the connecting portion 50d. The position where the horizontal blade 6A is connected by the connecting part 50d is that the axis connecting the connecting parts 51a, 52a connecting the left support arm 51 and the right support arm 52 is in the vicinity of the front end part 6Ad. The vicinity of the end 6Ae. Since the axis connecting the connecting portions 51a and 52a of the left support arm 51 and the right support arm 52 and the position of the connecting portion 50d of the swing arm 50b are displaced in the front-rear direction of the horizontal blade 6A, the rotating arm 50a is rotated. Accordingly, the horizontal blade 6A can be rotated. Further, since the swing arm 50b swings, the distance between the drive shaft on one end of the swing arm 50a and the connecting portion 50d of the swing arm 50b can be changed. On the other hand, the horizontal blade 6A can be moved in parallel by following the rotation of the rotation arm 50a. Thereby, the horizontal blade | wing 6A can take the attitude | position in which the upper surface 6Ai of main-body part 6Aa of the flat horizontal blade | wing 6A becomes horizontal, for example.

  The air direction device of the air conditioner includes a vertical blade driving mechanism in addition to the horizontal blade 6A and the vertical blade 9 described above and the horizontal blade driving mechanism for driving them. Control of the horizontal blade driving mechanism and the vertical blade driving mechanism will be described later. The vertical blade driving mechanism has the above-described vertical blade connecting rod 10 in order to drive the vertical blade 9. By adjusting the blowing direction of the horizontal blades 6A and the vertical blades 9 and adjusting the wind speed of the cross flow fan 7, the air flow of conditioned air for appropriate air conditioning corresponding to the indoor form and the indoor situation is generated. To do. In order to control the horizontal blades 6A, the vertical blades 9 and the cross flow fan 7, a control unit 20A as shown in FIG. 17 is provided. The control unit 20A includes an indoor control unit 21A for controlling each device of the indoor unit 1 and an outdoor control unit 22 for controlling each device of the outdoor unit. The indoor control unit 21A and the outdoor control unit 22 is connected by a signal line 23. Since the difference between the control unit 20 of the first embodiment and the control unit 20A of the second embodiment is only the difference between the indoor control unit 21 and the indoor control unit 21A, the indoor control unit 21A will be described below, and the outdoor control unit Description of 22 is omitted. In addition, the relationship between the transmission / reception unit 30, the crossflow fan motor 33, the temperature sensor 29, the display unit 35, and the like and the indoor control unit 21A is the same as that in the indoor control unit 21, and thus the description thereof is omitted.

  The indoor control unit 21A is connected to a transmission / reception unit 30, a horizontal blade driving mechanism 31A, a vertical blade driving mechanism 32, a crossflow fan motor 33, a temperature sensor 34, a display unit 35, and the like. The horizontal blade drive mechanism 31A controlled by the indoor control unit 21A includes a left support arm drive unit 36 and a right support arm drive unit 37 in order to tilt the horizontal blade 6A to the left or right. The indoor control unit 21A can drive the left support arm drive unit 36 and the right support arm drive unit 37 independently. When moving the horizontal blade 6A in parallel, the indoor control unit 21A controls the movement amount of the left support arm 51 and the movement amount of the right support arm 52 to be the same, and tilts the horizontal blade 6A to the left or right. In some cases, the movement amount of the left support arm 51 and the movement amount of the right support arm 52 are controlled to be different.

  Further, the horizontal blade drive mechanism 31A includes an intermediate support arm drive unit 38 for rotating the horizontal blade 6A. In order to release the horizontal blade 6A from the state where the blower 4 is closed and to make the horizontal blade 6A into a desired state, the indoor control unit 21A first uses the left support arm drive unit 36 and the right support arm drive unit 37. The left support arm 51 and the right support arm 52 are moved to push out the horizontal blade 6A. As a result, the air outlet 4 blocked by the horizontal blade 6A is opened. At this time, the intermediate support arm drive unit 38 follows the horizontal blade 6A so as to move in parallel, and rotates the rotating arm 50a. Move.

  Next, while the left support arm 51 and the right support arm 52 are fixed, the rotation arm 50a is rotated by the intermediate support arm drive unit 38, and the connecting portion 51a and the right support arm 52 of the left support arm 51 are rotated. The horizontal blade 6A is rotated around an axis connecting the connecting portion 52a. The horizontal blade 6A can be moved to a desired state by the two-step operation of the parallel movement and the rotational movement as described above.

  Note that the indoor control unit 21A controls the horizontal blade 6A to move to a desired state in one step by performing the two-step operation as described above in parallel and rotating while moving in parallel. You can also

<Operation of wind direction device>
In the operation of the wind direction device according to the second embodiment, when conditioned air is blown out from the outlet 4 with the horizontal blade 6A being horizontal, the following four operations are performed as in the first embodiment. Can be made. That is, about the right-and-left blowing in the state which closed the blower outlet 4 with the horizontal blade | wing 6A, or the blowing in the air_conditioning | cooling operation when the horizontal blade | wing 6A is a horizontal state, the blowing in the heating operation, and the blowing in the insensitive airflow mode The wind direction device of the second embodiment is the same as the wind direction device of the first embodiment.

(Blowout in insensitive airflow mode)
FIG. 18 shows a front state when the horizontal blades are tilted in the insensitive airflow mode, and FIG. 19 shows a state seen from the diagonal right side. 18 and 19 show a state where the left side of the horizontal blade 6A is lowered by extending the left support arm 51 longer than the right support arm 52. FIG. Further, since the insensitive airflow mode is in effect, the front end 6Ad of the horizontal blade 6A is slightly raised from the rear end 6Ae, and the upper surface of the horizontal blade 6A faces the air outlet 4. In other words, the posture of the horizontal blade 6A in the insensitive airflow mode is substantially the same as the posture in which the horizontal blade 6A closes the outlet 4 when the left support arm 51 and the right support arm 52 are extended to the same length. It is parallel, and when the left support arm 51 is extended long, the left side is further lowered from that state.

  When the vertical blade 9 is tilted to the left with respect to the longitudinal direction of the casing body 2 in a state where the left side of the horizontal blade 6A is lowered as described above, the air is blown out from the outlet 4 into the left slit 13 at the left end of the horizontal blade 6A. The conditioned air can be guided. At this time, since the horizontal blade 6A is inclined to the left, it is easy to guide to the left. Further, since the horizontal blade 6A is tilted to the left, the angle of the left side blowing guide plate 15 of the left slit 13 is further tilted downward, so that conditioned air flows in a zone closer to the left side surface 1b of the casing body 2. be able to.

  On the other hand, when the vertical blade 9 is tilted to the right with respect to the longitudinal direction of the casing body 2 while the left side of the horizontal blade 6A is lowered, the harmony blown from the outlet 4 to the right slit 14 at the right end of the horizontal blade 6A. Air can be guided. At this time, since the horizontal blade 6A is tilted to the left, the airflow of the conditioned air is further weakened because the airflow is returned along the horizontal blade 6A when guided to the right side. It becomes easy. Further, since the horizontal blade 6A is inclined to the left, the angle at which the right side blowing guide plate 16 of the right slit 14 is inclined downward is reduced, so that conditioned air can easily flow through a zone far from the right side surface 1c of the casing body 2.

  Even during the cooling operation, by tilting the horizontal blade 6A, the variation of the airflow in the left-right direction can be added in the same manner as the blowing in the insensitive airflow mode. As for the horizontal blade 6A during the cooling operation, the tip end 6Ad is lowered further than the position of the horizontal blade 6A in the insensitive airflow mode, but the appearance is similar, so illustration is omitted. If the vertical blades 9 are tilted so that the horizontal blades 6A are blown toward the inclined side, it becomes easy to blow out a fast air current. Moreover, since the angle of the left side blowing guide plate 15 or the right side blowing guide plate 16 is changed by the inclination of the horizontal blade 6A, the left and right blowing directions can be finely adjusted. On the other hand, if the vertical blades 9 are tilted so as to blow in the direction opposite to the direction in which the horizontal blades 6A are tilted, it is easy to blow a slow air current.

(Blowout during heating operation)
FIG. 20 shows a front state when the horizontal blades are tilted during heating operation, and FIG. 21 shows a state seen obliquely from the right side. 20 and 21 show a state in which the left side of the horizontal blade 6A is lowered by extending the left support arm 51 longer than the right support arm 52. FIG. Moreover, since it is during heating operation, the front end portion 6Ad of the horizontal blade 6A is lower than the rear end portion 6Ae, the rear end portion 6Ae protrudes forward from the vertical state of the horizontal blade 6A, and the upper surface is slightly lower. It is in a state of facing.

  When the vertical blade 9 is tilted to the left with respect to the longitudinal direction of the casing body 2 in a state where the left side of the horizontal blade 6A is lowered as described above, the air is blown out from the outlet 4 into the left slit 13 at the left end of the horizontal blade 6A. The conditioned air can be guided. At this time, since the horizontal blade 6A is inclined to the left, it is easy to guide to the left. Further, since the horizontal blade 6 </ b> A is inclined to the left, the conditioned air can easily flow through the left front side of the casing body 2 due to the angle of the left side blowing guide plate 15 of the left side slit 13.

  On the other hand, when the vertical blade 9 is tilted to the right with respect to the longitudinal direction of the casing body 2 while the left side of the horizontal blade 6A is lowered, the harmony blown from the outlet 4 to the right slit 14 at the right end of the horizontal blade 6A. Air can be guided. At this time, since the horizontal blade 6A is tilted to the left, the air flow of the conditioned air further weakens when it is guided to the right side, and the air flow of the conditioned air is further weakened. Further, since the horizontal blade 6A is inclined to the left, the angle at which the right side blowing guide plate 16 of the right slit 14 is inclined downward is reduced, so that conditioned air can easily flow through a zone far from the right side surface 1c of the casing body 2.

<Modification>
(1) In each of the above embodiments, the case where the wall-mounted indoor units 1, 1A, 1B are formed on the horizontal blades 6, 6A in which the left slit 13 and the right slit 14 are formed has been described. However, the indoor unit that can apply the horizontal blades in which the left slit and the right slit are formed is not limited to the wall-mounted indoor unit, and can be applied to a ceiling-mounted indoor unit, a stationary indoor unit, and the like.

  (2) In the first embodiment and the second embodiment, the left side surface portions 6b and 6Ab and the right side surface portions 6c and 6Ac are formed when the left slit 13 and the right slit 14 are formed or not formed. explained. That is, in the horizontal blades 6 and 6A, the states of the left side surfaces 6b and 6Ab and the right side surfaces 6c and 6Ac are fixed, and are not changed midway.

  However, a shutter that slides on the left slit 13 and the right slit 14 is provided, and is manually opened and closed, so that the state of the first embodiment and the second embodiment and the modification (1) is switched. You can also Further, the left slit 13 and the right slit 14 can be automatically opened and closed instead of manually.

  Furthermore, you may comprise so that the magnitude | size of the opening of the left side slit 13 and the right side slit 14 may be adjusted with a shutter. Thereby, it is possible to perform finer air conditioning according to the indoor state and environment.

  (3) In the first and second embodiments and the modified examples (1) and (2), as shown in FIG. 5, the left opening 12b and the right opening 12c of the outlet 4 are shown. Explained the case where a member that guides the airflow is not provided but the opening is simply formed.

  However, the guide shown in FIG. 22 can also be provided in the outlet passage 8 following the outlet 4. FIG. 22A and FIG. 22B are both perspective views showing a state in which the indoor unit 1B is viewed from the lower right side. FIG. 22A is looking up from the position moved further to the right side than FIG. 22B. The guide 60 provided in the opening 12c on the right side is a substantially plate-like member arranged horizontally, and guides conditioned air in the longitudinal direction of the air outlet 4 (longitudinal direction of the horizontal blades 6 and 6A). Therefore, a slit-like gap 61 is formed between the casing body 2 and the guide 60. 22 (a) and 22 (b) show only the right guide 60, the left side is provided with a guide for blowing to the left side symmetrically with the right side. Since the left guide has the same function as the right guide 60, the description of the left guide is omitted in the following description.

  When the right slit 14 is formed as in the horizontal blades 6 and 6A of the first embodiment and the second embodiment, the horizontal blade 6 is formed by inclining the vertical blade 9 and blowing conditioned air to the right. , 6A is closed, and conditioned air is guided from the guide 60 to the right slit 14. Therefore, the cooperation of the guide 60 and the right slit 14 facilitates the blowing of conditioned air in the right direction.

  When the horizontal blades 6 and 6A having the right slit 14 are slightly opened until the gap 61 of the guide 60 is not blocked by the horizontal blades 6 and 6A, the conditioned air is discharged horizontally from the gap 61 of the guide 60 to the right side. Simultaneously with the blowout, conditioned air can be blown out from the right slit 14 in the right direction. Therefore, more conditioned air can be blown rightward by the cooperation of the guide 60 and the horizontal blades 6 and 6A.

  Moreover, the horizontal blade | wing 6B can be inclined using the wind direction apparatus of the said 2nd Embodiment. In this case, by tilting, for example, by covering the left guide with the left side surface portion 6Bb, it is possible to blow out from the right guide 60 or blow out only from the right guide 60. In addition, for example, by combining the horizontal blade 6A and the guide 60 of the wind direction device of the second embodiment, variations in the flow of conditioned air in the right direction can be further increased.

<Features>
(A)
The horizontal blades 6, 6 </ b> A provided in the indoor units 1, 1 </ b> A, 1 </ b> B are provided in front of the air outlet 4. Here, the term “front” refers to a concept downstream of the air outlet 4 in the direction in which conditioned air is blown from the air outlet 4, and includes a case where the air is in contact with the air outlet 4 and coincides with the air outlet 4. . When referring to the front, the upstream of the outlet 4 is not included. Therefore, in the case where the outlet 4 is provided on the bottom surface 1e as in the above-described embodiments, it is in front of the outlet 4 even after the front surface 1a of the indoor units 1, 1A, 1B. The horizontal blades 6, 6 </ b> A provided in the indoor units 1, 1 </ b> A, 1 </ b> B can open and close the air outlet 4 and can change the wind direction of the conditioned air blown from the air outlet 4 up and down.

  A left slit 13 is formed near the left end of the horizontal blade 6.6A, and a right slit 14 is formed near the right end. By creating a flow of conditioned air in the left direction with the vertical blades 9, the conditioned air can be blown out in the left direction through the left slit 13. In addition, by creating a flow of conditioned air in the right direction with the vertical blades 9, the conditioned air can be blown out in the right direction through the right slit 14. Depending on the shape and formation position of the left slit 13 and the right slit 14, the conditioned air flow passing through the left slit 13 and the right slit 14 blows off in the left-right direction only by hitting the upper surfaces 6i and 6Ai of the horizontal blades 6 and 6A. Since these are different from the conditioned air flow, the variation of the air flow can be increased by utilizing these differences.

  In addition, the above-mentioned left side slit 13 is divided | segmented up and down, and consists of the upper left slit 13a and the lower left slit 13b. The right slit 14 includes an upper right slit 14a and a lower right slit 14b. However, the division of the left slit 13 and the right slit 14 is not essential for the invention. In other words, the shape of the slit may be different from that described above, and is appropriately set according to the required performance. As the shape of the slit, various methods such as changing the way of dividing such as front and rear, making the outer periphery of the slit elliptical or circular, and making the number of divisions three or more are conceivable.

  For the upper left slit 13a, the slope 6k and the left side blowing guide plate 15 correspond to a side blowing guide part. And with respect to the lower left slit 13b, the left side blowing guide plate 15 corresponds to a side blowing guide part. Therefore, the side blowing induction part of the left side slit 13 is the slope 6k and the left side blowing induction plate 15, and any one of these functions as the side blowing induction part. Similarly, the side blowing induction part of the right side slit 14 is the slope 6l and the right side blowing induction plate 16, and any one of these functions as the side blowing induction part. The slopes 6k, 6l, the left side blowing guide plate 15 and the right side blowing guide plate 16 serve to facilitate the induction of conditioned air into the left slit 13 and the right slit 14, but not only that, but along the direction in which the surface faces. It also plays a role of forming a conditioned air stream and blowing it out in a desired direction. The slopes 6k and 6l, the left side blowing guide plate 15 and the right side blowing guide plate 16 are also members that determine the side blowing direction in the sense that they play a role of blowing in a desired direction.

  The left side slit 13 is formed in the left side surface portion 6b, and the right side slit 14 is formed in the right side surface portion 6c. A left side surface portion 6b is formed at the left end of the main body portion 6a so as to bend toward the outlet 4 rather than the main body portion 6a. That is, the left side surface portion 6b is warped toward the blowout port 4 rather than the main body portion 6a. Therefore, the left side surface portion 6b becomes an obstacle to the conditioned air that goes to the left side along the main body portion 6a and tries to blow out to the left side. Since the left side slit 13 is formed in the left side surface part 6b which becomes the obstacle, a part of the conditioned air blown out to the left through a place other than the left side slit 13 can be restricted. As a result, the conditioned air passes through the left slit 13 in a concentrated manner and can be blown out strongly while restricting the area of the conditioned air flow blown out to the left side, on the wall to which the indoor unit is attached. It becomes easy to perform the air conditioning of the area along.

  The above-described horizontal blades 6 and 6A are controlled by the control units 20 and 20A, and the control units 20 and 20A can block the air outlet 4 with the horizontal blades 6 and 6A. And the control part 20 and 20A can drive the motor 33 for crossflow fans in the state which the horizontal blade | wings 6 and 6A block | closed the blower outlet 4. FIG. When the crossflow fan motor 33 is driven, the portions other than the left slit 13 and the right slit 14 are closed, so that conditioned air can be blown out only from the left slit 13 and the right slit 14. In addition, since the other portions are blocked, the conditioned air that is blown out concentrates on the left slit 13 and the right slit 14, so that it is possible to blow out strongly.

(B)
Conditioned air can be guided in the horizontal direction of the horizontal blades 6 and 6A by the right guide 60 shown in FIG. 22 and the left guide not shown. Since the right side guide 60 and the left side guide are in the blowout passage 8 (the space covered by the horizontal blades) that is closed when the horizontal blades 6 and 6A are closed, they do not appear in appearance when the operation is stopped. This makes it easy to design for a sophisticated appearance.

  In the horizontal blades 6 and 6A, unlike the case where the right guide 60 and the left guide are not provided by the cooperation of the right guide 60 and the left guide, the horizontal direction of the conditioned air is different. Can be efficiently blown out. When the horizontal blades 6 and 6A are closed, a conditioned air flow path guided from the right guide 60 to the right slit 14 can be formed, and a conditioned air flow path guided from the left guide to the left slit 13 can be formed. When the horizontal blades 6 and 6A are opened, the conditioned air is blown out to the left and right by the air flow formed by the right guide 60 and the left guide together with the conditioned air flow guided by the horizontal blades 6 and 6A and guided in the left-right direction. Is done. Thereby, compared with the case where the right side guide 60 and the left side guide are not provided, it becomes easier to blow out the conditioned air in the left-right direction.

(C)
In the indoor units 1, 1 </ b> A, 1 </ b> B, it is possible to create a state where the horizontal blades 6, 6 </ b> A cover the air outlet 4 but the horizontal blades 6, 6 </ b> A do not block the air outlet 4. That is, there is a gap between the periphery of the horizontal blades 6 and 6 </ b> A and the periphery of the air outlet 4. Even in such a state, if the gap is narrowed, a close state can be created when the gap is closed. If there is a gap, the conditioned air can be blown out from the gap, and not only the left-right direction but also the conditioned air flow toward the front can be created at the same time. Since the adjustment of the distance between the periphery of the blower outlet 4 and the horizontal blades 6, 6A, 6b is diversified, there is an effect of increasing variations in control such as the wind direction and the wind speed. Thus, it is possible to create a state in which there is a gap between the periphery of the horizontal blades 6 and 6A and the periphery of the blower outlet 4 by pushing out the horizontal blades 6 and 6A. For that purpose, a mechanism such as the horizontal blade driving mechanism described in the first and second embodiments is required.

  The horizontal blade driving mechanism can guide conditioned air in the four directions of front, rear, left and right by the arms 40, 41, 42, the left support arm 51, the right support arm 52 and the rotating mechanism described with reference to FIGS. The main body portions 6a and 6Aa, the left side surface portions 6b and 6Ab, and the right side surface portions 6c and 6Ac can be pushed out to a ready state. Although the same amount of conditioned air is not blown forward and backward, the conditioned air can be adjusted by the horizontal blade drive mechanism so that the conditioned air can be guided in the four directions of front, rear, left and right. It is easy to adjust the horizontal blades 6 and 6A at an angle that creates a state in which the air flows easily. Taking the horizontal blade 6 as an example, by making a fine adjustment such as tilting the tip 6d slightly as shown in FIGS. Air conditioning can be performed in a quiet state where it is difficult for a person to feel the flow. In a situation close to a desired air-conditioning state set by a remote controller or the like, air-conditioning can be performed in a highly quiet state, and comfort of air-conditioning can be improved.

  As described with reference to FIGS. 16 to 21 for the indoor unit 1A according to the second embodiment, the horizontal blade driving mechanism of the second embodiment can tilt the main body 6Aa to the left or right. In addition to causing the vertical blade 9 to blow out conditioned air strongly to the left, right or both sides, the direction of the reaction that the conditioned air receives from the main body portion 6Aa is determined by the inclination of the main body portion 6Aa. When tilting the part 6Aa, the force blown out increases. Conversely, if the main body 6Aa is tilted in the direction opposite to the blowing direction determined by the vertical blades 9, the force with which the conditioned air is blown out is weakened. For example, if the main body 6Aa is tilted to the left so that the left is lowered when the conditioned air is blown to the right by the vertical blades 9, the air flow of the conditioned air blown toward the right becomes weak. In this way, by configuring the main body 6Aa to be tilted, it is possible to finely adjust the airflow of conditioned air that blows to the left and right, and to increase the variation of the airflow, so that air conditioning that matches the indoor situation is performed. It becomes easy.
